If this is all your code, try using just:
class nothing(Exception): pass
if __name__ == "__main__":
raise nothing
Exceptions are built-in since aeons ago, so you don't have to import the
exceptions module.
The standard Exception class has an "args" attribute, and it's expected to
be a tuple (not None). See
<http://docs.python.org/lib/module-exceptions.html>
